Specification of Letters Patent. Application filed. July 5, 1913. Serial N 0. 777,532.

Patented Sept. 1,1914.

To all whom it may concern: l Be it known that I, J OHN S. PURDY, -a cltlzen of the United States, residing at Houston Heights, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Picket-Point ers, of which the following is a specification.

This invention relates to new and useful improvements in a picket pointer.

The object of the invention is to provide a device of the character described whereby the picketsuscd in the construction orwoven wire picket fences may be sharpened or beveled at one end uniformly and with ease and despatch.

With the above and-"othe-robjects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specificationand. illustrated in the accompanying drawings, wherein- Figure l is a plan view of the device. Fig. 2 is a side elevation thereof, and Fig. 3 is an end elevation thereof.

Referring now more particularly to the drawings wherein like-numerals of reference designate similar parts in each of the fig ures, the numeral 1 refers to a U-shaped casting forming the frame work of the device and which is adapted to be secured to a suitable stationary support. Upon the side of this frame work, near one endthereof is secured a blade 2. This blade is secured in position and may be adjusted in accordance with the desired angle of the point of the picket. The other end of the frame work has a suitable bearing 4 integral therewith and passing through this bearing 4 is a bolt 5 which also passes through suit able holes in the links 6 and 7 These links are secured in position by means of said bolt, one end of which has an integral head and the other end of which has a nut threaded thereon. The other, or upper ends of the links 6 and 7 embrace the dog 8, one being arranged on each side and passing through said ends of said links and also through an alined bearing in said dog is a bolt 9, one end of which has an integral head and upon the other end of which is threaded a nut so as to hold said links in position relative to said dog. This dog is arranged to oppose the'blade 2 and is spaced a distance there from and its top facing the blade is provided then forced with sharp teeth after set forth. I A handlelOis provided, one end of which is inserted' in the socket'll of the'dogS and y means ofwhich' said dog i's inani'pulated.

for a purpose to be herein- Secured upon the handle near-its free end is aginde plate 12 which can be adjusted for .pickets. One side and different lengths of g the outer end of this plate is providedwith upstanding flanges numbered respectively 13 2ll1d- -a In operation the pic ets are placed side by side, the outer ends restinguponthe plate 12 and" against the flange 14.- The other ends of these picketsre'st upon the-dog 8 and project between the 'sanieand the blade 2. The han dle lO andthepickets carried thereby'are downwardly so as to bring the ends of the the dog 8 operating upon its 6 and 7 operbolt 5 as a pivot. The'blade 2 1s set at such an angle with referenceto the handle 10 that the corners of the pickets will be cut, ofi by said blade, and the blade is ating upon the of sufficient width to cut off all the corners of the pickets carried by the plate 12. The position of the pickets is then reversed, the other edges being placed toward the handle 10, the operation completed and the other corners of said pickets cut off. In forcing the pickets against the blade 2 the cutting edge enters the'side of the picket and follows the arc of a circle whose radius is very nearly equal to the distance from the pivot point of the bolt 5 to the cutting edge of the blade 2. The point of the picket will be the intersection of two arcs of two equal circlesl The upper side of the dog facing the blade 2 is provided with ratchet teeth which engage with said pickets and prevent them from slipping during the operation of the device. f

The link 7 bolt 9 and downwardly beyond the bolt 5, the upwardly projecting end of said link, together with the flange 18 forming side braces for the pickets during the operation of the device, and the lower projecting end of said link 7 limiting the rearward movement of the handle 10" by coming in contact with the lug 15,,projecting" outwardly from the frame work l.' Projecting later-all from the frame work 1 is a bearing mem er 16 which has a tapped hole extending there I pickets a ainst the sharp ed ev of; said blade, 6 a pivotal support and the links projects upwardly beyond the belt 17 in its bearing 16 determines the posiends of said links pivoted thereto and arends of said links pivoted thereto and arranged to oppose said blade and spaced therefrom, one end of one of said links projecting upwardly beyond said dog and forming a. lateral brace, a handle secured to said dog for manipulating the same and a supporting plate secured to said handle near its free end.

3. A device of the character described, including a frame, a cutting blade fixed to said frame, a pair of links pivoted to the frame at one'end', a dog between the other ends of said links pivoted thereto and arranged to oppose said blade and spaced therefrom, one end of one of said links projecting upwardly beyond said dog and forming a lateral brace, means for regulating the position of said dog, ahandle secured to said dog for manipulating the same and a supporting means securedto said handle near its free end.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

through through which the outwardly threaded bolt 17 is screwed whose end is in alineinent with a cross bar 18 carried by the links (3 and T. The adjustment of the tion of the dog 8 just before the blade enters the pickets and consequently determines the curve at which the corners of the pickets are taken oii.

What I claim is':

1. A device of the character described, including a frame, a cutting blade fixed to said frame, a pair of links pivoted' to the frame at one end, a dog between'the, other ranged to oppose said blade and spaced therefrom, an adjustable member carried by the frame for engaging and limiting the movement of said links and the dog carried thereby, ahandle secured to said dog for manipulating the same and a supporting plate secured to said handle near itsfree end.

'2. A device of the character describedincluding a frame, a cutting blade fixed to said frame, a pair of links pivoted to the frame at one end, a dog between the other \Vitnesses MAY MONTGOMERY, J. C. CARPENTER.
